I have considered rebuilding the pump myself before. Doesn't seem too
difficult looking at Bentley. But I have read here and been told by my
trusted mechanic at the Audi dealer that rebuilding the pump is usually
not very successful unless done by the manufacturer or professional
rebuilders who do it all the time. If the rebuilding is not done right,
the leaks start up again, especially considering the high pressures
it is operating under. I have successfully rebuilt a GM (Cadillac)
PS pump but I think the Audi pump is a very different beast altogether.

Let us know how you make out if you attempt it.
